Thunderbird renders images too large - ignoring the defined height (ongoing issue, at least since version 128.7.1esr)

Hi everyone,

We've been experiencing an issue with image rendering in Thunderbird for quite some time. Since at least version 128.7.1esr (and possibly earlier), images in emails are displayed at their maximum size, ignoring the defined height. When you resize the email window in Thunderbird, you can see, that the height of the image is switchting between the defined height and ignoring the height.

This issue occurs only in Thunderbird—other email clients and webmail services display the images in our mails correctly. Originally, we used the following code in our signature in our company:

Since Thunderbird seems to ignore the height attribute, we started using a style declaration with "!important" as a workaround:

This problem affects any embedded images in emails.

Has anyone else encountered this issue or knows when this will be fixed? Any insights would be greatly appreciated!

Thanks in advance!

Because the code is not displayed in the original post, I post here a minimal example:

The attribute 'height="40"' inside an img-Tag is ignored.

Our workaround is 'style="height: 40px !important;"' inside an img-Tag.

It seems like a rendering-bug for me.
